Time Out says
The entire zoo is transformed into a Halloween paradise for thrill seekers and tame trick-or-treaters alike. Families can embark down a Candy Land path in search of sweet treats or explore an enchanted forest or try your hand at Zoo Family Feud. Rub shoulders with clowns, cave people and aliens around the grounds before you participate in carnival games and compete in the costume contest. Advanced tickets required and go on sale Sept 4. All ages.
